These figures cover 364 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

When UA 318 flies
UA 318 is scheduled to leave Denver (DEN) at 11:15 local time and reach Eugene (EUG) at 13:07. That slot held for 340 of the 364 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Across the year
UA 318 quarter by quarter
UA 318 did not run the same all year. Its best quarter was Jan–Mar 2026 at 77.3% on time and its weakest Jul–Sep 2026 at 61.3%, a swing of 16 points on roughly 73 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202592 flights76.1%
- Jan–Mar 202689 flights77.3%
- Apr–Jun 202691 flights64.8%

Scale runs 55% to 85%.
By weekday, UA 318 did best on Thursday at 80.8% on time and worst on Wednesday at 56.9%. Each day rests on about 52 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Share of 363 completed flights by arrival against schedule.
8 of 62 late departures made up the time and arrived on time, 13% of them. In the other direction, 51 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at EUG.
The worst days
Worst days for UA 318
The latest arrival of the period was on 19 December 2025, 3 hours 44 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 December 2025 | 3 hours 44 minutes | Late-arriving aircraft |
| 30 November 2025 | 3 hours 31 minutes | Late-arriving aircraft |
| 9 November 2025 | 3 hours 3 minutes | Carrier |
| 28 December 2025 | 1 hour 50 minutes | Late-arriving aircraft |
| 15 June 2026 | 1 hour 34 minutes | Late-arriving aircraft |
Delay causes
Why UA 318 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,226 reported delay minutes.
- 37%National Airspace System
- 35%Late-arriving aircraft
- 28%Carrier
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,226 reported delay minutes here, that single category outweighs weather by 35 to one. The split is drawn from 4,226 delay minutes reported on UA 318.
Cancellations are rare at 0.27%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
5.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 40 minutes, which a normal layover absorbs.
The 996 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on six other city pairs in the data, including RSW to DEN (60), MIA to DEN (31) and MSY to DEN (24), but none flew often enough under UA 318 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to EUG only.
One caution: this is a thin sample. 364 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking UA 318
For a booking, read UA 318 as 71.1% on time with 0.27% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
